I hate it when that happens...

In order to lure my nine year old away from Grandma's house and her X-Box, I dangled the prospect of turning a bowl in front of him. I had glued one of Dave in Fairfax's generous bowl blank offerings to a glue block the night before. I finally felt worthy of taking a crack at a piece of my beloved and treasured walnut, and this was the only blank I had prepared for turning. I had some reservations about letting the boy turn my precious walnut as his first bowl, but I weighed this against the idea of leaving him to play that stupid video game for the rest of the day, and decided to go ahead and let him do it.

So off we go to the lathe. He had demonstrated serious aptitude for spindle work, but had never approached a bowl before. I explained the concepts involved, held his hand for a bit, and then went to the other side of the shop to work on cleaning up a few messes. I just let him have at it, looking over at him from time to time.

Once he had done a pretty good job of shaping the outside, I went back and refined it just a smidge. Then we started in on the hollowing phase. I once more let him have at it while I built a handy dandy depth gauge gadget.

After hogging out most of the waste, we took turns refining the walls and bottom, using my depth gauge thingie to get the depth just so, and feeling our way carefully to keep the walls smooth and even.

He was satisfied that it was done, but Daddy wanted to refine it just a smidge more, until it was perfect.

Then we sanded, sanded, sanded some more. I carefully dressed a couple of rough tearout patches with a scraper I made out of an old bench chisel, then we sanded some more. We went from 100 all the way up to 2,000 grit, and the wood was so smooth when we were done that it looked to have been finished already.

Then we got out the beeswax, rubbed some on, then melted it in with a cloth. The bowl came alive as soon as that happened, becoming more gorgeous with each press of the cloth.

Then I set the speed for 500 RPM and began to part off the last bit of the bottom.

WHACK!

It tore loose and went sailing into the wall, leaving a 1" diameter hunk of walnut stuck to the glue block.

Daddy had gotten the bottom too thin, and when I parted it off, I only left

1/32" of wood in the bottom of the bowl. It wasn't enough to handle the stress once I got down that far into it, and the bowl was lost.

Damn, damn, damn, damn, damn!!

The up side is that it didn't crack when it hit the wall. It's a beautiful little walnut bowl with a 1" hole in the bottom. I guess we'll make it a container to hold a silk flower arrangement or something.

I'm still proud of the boy in any event. He's a natural turner. He'd do better with a real teacher, instead of the blind leading the blind, but this is what we have to work with. In my judgement, he's doing *just* fine.

I'm going to have to buy a full-sized lathe and give him this mini sooner rather than later, I suspect, or at least buy him his own mini. I can see that it won't be long before we're fighting over the lathe. :)

It's a shame about his bowl though. A real shame. :(

But a good day still. I sure never did anything like this with my own Dad. He and I did some things together to be sure, but never anything like this, and not nearly so often.

Spindle turn a pedestal base for it. Turn a 1" tenon to fit the conveniently sized hole fate left you ;-)

The caliper I sent has a depth rod built into it. Try using that, with the lathe stopped, and leave yourself 1/2" of bottom. After you part it off, there'll be a lot less than that. Don't worry about the bowl, there's more where that came from. I'm glad nobody got hurt.

Great story. I've got a few bowls like that myself. Why not make the hole a bit larger and round it out- turn a contrasting color plug to fit and make it a "feature".

My son isn't into spending shop time with dad anymore. He's doing metal sculpture in school and wants a welder and sand blaster to play with. SIGH. If only I could convince his mother that it's in his best interest to get him those- with the metal lather and mill .

Your mother (-in law?) has an X-Box?

Where do you live that walnut is so scarce and precious?

Too bad about the bowl. I've had almost exactly the same thing happen, and have a small collection of "coarse collanders" to attest to it.

In order to lure my nine year old away from Grandma's house and her X-Box, sounds like one lucky nine year old I had some reservations about letting the boy turn my precious

If only all nine year olds were this lucky in their choice of parents:-)

thats either very generous, or very self serving of you, getting two lathes and having a good rxcuse to do it(joking)

Mother. Yeah. She's a real video game junkie. Like I used to be when I was 14 years old. I grew out of it. She grew into it. Go figure.

At this point, bowl blanks are precious because I haven't been able to secure any suitable supplies of turning wood. All wood is precious except for 1-2" maple branches, which I have in copious abundance.

I have a bunch of bowl blanks that Dave in Fairfax kindly sent to tide me over until I get the wood flowing in. Not too many of them are walnut. Walnut is also my absolute favorite wood, so I value it more than the rest of the short supply I have.

Coarse collanders... I like that.

That's a great idea! Good way to use a scrap of 4/4 walnut about 6" long too, now that I think about it.

I'll have to file this trick away.

You could use a jam chuck or a "doughnut" chuck to clean up the hole. I would make the plaque out of an attractive contrasting wood, so it doesn't look like an effort to hide a patch. Or, you could go to a trophy shop and have one engraved in brass.

Or, you could turn an insert out of the same wood, and conceal the seam by turning some circles at the edge. In any case, I would not leave this kid with a failure as the result of all that you did together.

Why is that the bottom has to be as thin as possible? I agree that walls should be thin (and even depending on the prupose/not too thin for a food bowl), but leaving the bottom with 1/2 " thickness would not really matter would it?

I usually do this with my large bowls. It gives the bowl two useful characteristics: First, it looks delicate because the rim is so thin. Second, it feels strong, because the total mass is higher than you'd expect from seeing the rim.

But mostly I do it because I need more practice ;-)

It depends on the style of the object and its size. On a 12" bowl,

1/4" would be "thin" for me, with 1/2 to 3/4 being "thick". It also depends on the treatment you give the rim (decorations, bands, etc).

Because thick walls make the bowl look chunky and unappealing.

Because if they're too heavy they're unwieldy. And ugly.

Good luck!

That's a neat idea. Have him write it with resist ink and etch it onto a brass disc.

We're going to fix the bottom with a pedestal made out of either walnut or maple, depending on what he decides.

Yeah, and to add insult to injury, the dog ate his Pinewood Derby car on the very same day.

Poor little feller... :(

Or, instead of using a matching wood, go with a contrasting wood, say lightly figured maple.

Just a thought

Definitely

Actually, it sounds like a great day to me...you spent some good time with the kid. THAT in and of itself, has to be worth it!

OK, so you ended up showing the boy that Dad is human after all, but that really isn't all that bad.

Just as long as your wife never finds out you're human, the kid will keep your secret.

Any excuse I can find to drag him away from that video game for awhile. :)

Taught him some important lessons about failure too, maybe. When the dog eats your car, you get out a block of wood and start over.

That thing might even win this year. It's almost certain to be the only

*turned* pinewood derby car on the field.

Dunno - I spent a lot of time fiddling with the body (sleekly areodymnamic) on mine 30 odd years ago, ran it up to maximum weight, and as far as I recall, the winner was an ugly block which perhaps had a lot of extra effort on getting the wheels to spin well.

We were #2, right after the guy who always wins. We still wouldn't have beaten him, but we would have won a few more races if it hadn't been for the pointy rocket nose on the thing. It lost at least two very close heats because the point didn't trigger the electric eye immediately.

I'm satisfied with #2. As far as I'm concerned, we can retire now. Next year's car can be crappy, and let some other kid win a trophy next time.

I don't know if my son will see it that way though. :)
